IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed‚ there is no way that human beings can survive. From the oxygen that we breathe in‚ the food that we eat‚ to the clothes we wear‚ we owe it all to the trees. Not only this‚ trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel‚ fodder‚ timber‚ medicines and numerous other valuable products from the trees. It is‚ therefore‚ not surprising that trees

are actually doing this today. There are many benefits to cloning people‚ animals and plants. There are lots of ways in which cloning can be beneficial to us. A few examples of how cloning can help us solve problems are by genetically producing humans to test out new medicine for diseases‚ cloning organs for transplants‚ weapons‚ and help us in war. This can also benefit us in farming. We can create new plants‚ fruits‚ vegetables‚ and flowers. This would help starvation in third world countries

Individual plants and animals could not exist by its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water

many reasons to grow indoors over outdoors. There is the freedom to choose the location you want to grow in with very little constraints and the ability to control your environment and the growth of the plant are just a few. Indoor farming allows for complete control over the environment the plant is in. The controlling of the temperatures‚ light sources‚ CO2 productions‚ and humidity creates a stable habitat for the plant’s growth without having to risk outdoor elements. When growing indoor you
