Summarize the following:
Some locations may not let you to have a rainforest, especially very cold climates. Consider the limitations (and opportunities) of where you live when planning your urban rainforest.  Determine your city’s geographical region. Mountainous regions may require a different landscape design than flatter areas. Consider local plants in addition to more typical rainforest plant life. Know the best plants for your climate. If you live in a colder region, choose plants that can survive in that climate.   Plan an enclosed greenhouse if you want to choose a more tropical rainforest theme in a colder geographical location. However, realize that this will be more expensive. Know both the big picture and small details that make up your urban rainforest.  Consider your visitors. Make sure your urban rainforest is a fun and safe space for everyone. Design your urban rainforest to be child-friendly and accessible. Try not to keep anyone from enjoying your hard work. Insure your rainforest. You want to protect yourself and your visitors in the case of injury.   Follow through on safety measures. Staying safe is always better than regretting it later. Don't buy the land yourself. Find people and institutions that can donate land for your urban rainforest.  Scout locations in your city. Find any vacant lots to see if that land is being used.   Check in with the city government or local neighborhoods to see if any land is available to develop into an urban rainforest. They may be looking for ways to improve unused land.  Be open-minded about how big or small your project may be. Think about how your idea can fit into different plots of land.
Consider the geography and climate. Weigh the practicalities. Seek free or donated land.
