1. Forests remove carbon dioxide from the atmosphere and store it in organic compounds, they help to stabilize the earth’s temperature, and they slow global warming as a part of the global carbon cycle. The economic value is that 80% of medicines come from forest’s plants, they are habitats for about 2/3 of the earth’s terrestrial species, and they are home to more than 300 million people- and more than one of every four people depend on forests for their livelihoods.
2. You can ban imported timber that might introduce harmful diseases or insects. Another is to remove or clear-cut infected and infested trees. Also, we can develop tree species that are genetically resistant to common tree diseases, or control insect pests by applying conventional pesticides.
3. The burning of tropical forests is said to account for at least 20% of all human-created green-house gas emission. Widespread fires in the Amazon are changing weather patterns by raising temperatures and reducing rainfall. This is converting deforested areas of tropical grassland, which is an irreversible ecological tipping point. They project that if deforestation rates continue, then 20-30% of the Amazon will be turned into savanna in the next 50 years and perhaps all by 2080.
4. Haiti is experiencing an ecological disaster because all its trees have been cut for fuelwood and now is only 2% forest. It is also focused in Latin America, Indonesia, and Africa. Deforestation is the temporary or permanent removal of large expanses of forest for agriculture, settlements, or other uses. Deforestation creates a major loss of habitat, erosion, and large emissions of carbon into the atmosphere, therefore helping to induce global warming.
5. Population growth, poverty, and government policies are all major causes of deforestation. The building of roads, logging, and the growing of cash crops are all things that we as humans do to destroy the tropical forests.
6. The Green Belt Movement is where women are paid a small amount of money for each seedling that they plant that survives. This lets them break the cycle of poverty while also improving the environment. We can help new settlers in tropical forests to learn how to practice small-scale sustainable agriculture and forestry, harvest some of the renewable resources on a sustainable basis, debt-for-nature-swaps, and loggers can use tropical forests more sustainably by using gentler methods for harvesting trees.
7. There are surface fires and there are crown fires. Surface fires can be ecologically beneficial by destroying flammable ground material to help prevent more destructive fires, they free valuable mineral nutrients tied up in slowly decomposing litter and undergrowth, and wildlife species depend on occasional surface fires to maintain their habitats and provide food in the form of vegetation that sprouts after fires.
8. The first approach is to set small, contained surface fires to remove flammable small trees and brush in the highest-risk forest areas. Second, is to allow many fires on public lands to burn flammable brush. Third, you can protect houses and other building in fire-prone areas.
9. Overgrazing is when too many animals graze for too long and exceed the carrying capacity of a range-land area. Undergrazing is where there is an absence of grazing for long periods of time and can reduce the net primary productivity of grassland vegetation and grass over. In order to control it, the most effective way is to control the amount of animals that can graze in a certain area and also put a limit to how long they are able to.
10. Popularity, migration or introduction of non-native species, illegal removal of animals, pollution, and underfunded parks are all threats to the US’s national parks. National parks could integrate plans for managing parks and nearby federal lands, add new parkland near threatened species, or buy private land inside parks- all of those things
