In one sentence, describe what the following article is about: There are multiple types of pine trees, but as members of the same broad family, they tend to share similar characteristics. Look for tall trees with needles and cone type fruit to find a pine tree.  Loblolly pine trees are tall trees, usually reaching heights between 98 and 115 feet (30 to 35 m). These trees have needles that are usually found in bunches of three, and the trees produce cone-type fruit. The bark is scaly, and the branches are largely clustered at the top of the tree.  Lodgepole pine trees are thin, narrow trees reaching heights of 130 to 160 feet (40 to 50 m). The top of the tree tends to be flattened, but they also have needles that come in clusters of two and cone-type fruit. As with pine trees, there are a few different variations of fir tree within the fir species, even though most do share similar traits.  Douglas fir trees are one of the tallest tree types in the world, growing up to 250 feet (76 m) tall. The bark is thin and smooth on young trees but thick and corky on old trees. These trees produce cone-like fruit with a narrow shape and red-brown scales, and the needle-like leaves are arranged in spirals, lying flat along the shoots. The top of the tree is somewhat cylindrical.  Balsam fir trees are a smaller variety, reaching heights between 46 and 66 feet (14 and 20 m). The top of the tree is narrow and pointed, giving the overall shape a conical appearance. The bark is smooth and gray on young trees but rough and scaly on old trees, and the leaves are needle-like. The cones ripen to a brown color but disintegrate and release winged seeds in the fall. Oak trees are usually divided into a white oak group and a red oak group, but other variations exist as well.  White oak trees have simple, lobed leaves without bristled tips. They produce acorns, and the bark is usually a light gray color with a scaly appearance.  Red oak trees also produce acorns, but they have lobed leaves with bristled tips. The bark is scaly and a dark red-gray to red-brown color. The branches are thin and initially appear bright green before turning dark red and, eventually, dark brown. Maple trees are all fairly similar, but there are also multiple types within the broader species.  Sugar maple trees have five rounded leaf lobes. In the spring and summer, the leaves are green, but they turn bright yellow, orange, or bright red-orange in fall, and the fall coloring tends to be uneven. The bark has ridges in it and the fruit it produces is winged.  Silver maple trees have sharp leaf lobes that are deeply cut. While vibrant green during the summer, the leaves are only a pale yellow in the fall. The bark tends to be smooth and silver on young trees but gray and shaggy on old trees.  Red maple trees have sharp leaf lobes that are shallowly cut. The leaves are green during the summer but usually turn a vibrant shade of red during autumn. The bark of the tree is smooth and pale gray in young trees, but older trees get darker bark with a plate-like texture. Red maple trees also produce double-sided winged fruit. Birch trees are used fairly commonly as decorative or ornamental trees due to their colorful bark and exposed trunks. Look for papery bark that wraps around the tree, lobed leaves with points around the outside and small, fragile cones attached to the branches to identify a birch.  Paper birch trees will have white, very papery bark and can grow up to 70 feet (21 m) tall.  Red or water birch trees have a darker, reddish-brown or copper colored bark. They also tend to be much smaller, between the size of a shrub or up to 30 feet (9.1 m) tall. Sycamores are giant trees, used both to decorate a broad landscape and to provide a spot of shade on a particularly hot day. To identify a sycamore tree, look for large, leathery green leaves and small green flowers attached to its branches. The bark will generally be a mixture of whites, tans, and browns, although these colors might be covered with a thin layer of white bark. If you’re trying to find a sycamore tree, look up! Sycamores can grow up to 100 feet (30 m), with a canopy of leaves covering a 70 feet (21 m) diameter.
Summary: Identify a pine tree. Spot a fir tree. Know what an oak looks like. Familiarize yourself with the maple tree. Recognize a birch tree. Spot a sycamore tree.

Problem: Article: It is a myth that you are "putting the idea in their heads." If someone displays the warning signs of suicide, you need to talk to them. You need to be simple and direct, asking them if there is any chance that they hurt themselves. You need to have an open conversation about suicide, as hard as that may be. Some good ways to ask include:  "Have you considered hurting yourself?" "Do you know how you would do it?" "Are you planning on committing suicide?" You cannot, and should not, shoulder this burden alone. Even if your friends swears you to secrecy, you need to break the oath and let someone know. This person can be a hotline staff member, a counselor, or a trusted adult. You need to enlist the support of trained, responsible people who can help your friend far better than you can.  Call the National Suicide Prevention Lifeline at 800-273-TALK (800-273-8255) to talk through this difficult time and find strategies for helping someone. If you'd be more comfortable messaging someone, connect with a trained crisis counselor by texting the Crisis Text line at 741741 in the US. If you're in Canada, the number is 686868, and in the UK the number is 85258. Push them to call a hotline, see a counselor/therapist, or join a support group. Help them see that there is no stigma to therapy, and that there is no reason to feel ashamed of getting help. You need to get them talking to someone about their thoughts, and mental health experts are trained to help prevent tragedies like this. Offer to support them through their therapy. Join them at appointments, help them do research, and/or drive them to and from meetings. Ask the person what they enjoy doing and what helps them to feel relaxed. This might include a special interest, hobby, or doing something calming, such as taking a long bath. Encourage them to make time for these activities as part of a regular self-care routine and let them know that this may help them to relieve stress, develop more resilience, and feel better in general.For example, they could set aside 30 minutes daily to go bird watching if that’s something they enjoy, or designate the last hour before bedtime as their bath and beauty hour where they draw a luxurious bath and take their time relaxing. If, in response to your question "do you know how you'd do it?" you get a response, you should not leave their side. If they have a plan in place, then they are far down the road of suicidal thoughts and should have constant support. If you do need to leave them, and they do not seem likely to commit suicide soon, you should still get them to talk to someone, even if just over the phone, before you go. This is another reason you 'must tell other people that they are considering suicide. A big support system is one of the best ways to prevent a tragedy. Take away any weapons, blades, or prescription drugs. In addition, keep them away from alcohol and other drugs, as these can influence people to act in ways they may not sober. Enlist other friends or family members to help you keep an eye out for dangerous objects and get them out of the way.
Summary:
Ask if they consider killing themselves. Talk to a professional. Suggest different people for them to see for therapy. Encourage them to practice regular self-care. Stay with them if you are worried that suicide may be imminent. Remove dangerous substances and items from their houses.
