28/30000,000 species are found in the rainforest 99% of which are insects destation is destroying their habitats endangering the species some of which are valuable
Many medicines can also be found in the rainforest such as periwinkle which has reduced deaths from child leukaemia from 80% to 20%
Many rivers that supply villages have also been polluted due to mining operations making the water unsafe to use yet the people still do as they don't have an alternative
There has been a huge reduction in the number of our Ameridians from 6,000,000 to 200,000 causing damage to their culture and way of life other tribes are often forced to live in reservations
The lack of trees also causes soil erosion and stops roots being able to bind together because there is no canopy to protect the ground from heavy rainfall this leads to nutrients being washed away leaving the soil infertile

Human activities such as deforestation increase the rate of climate change. Given the basic principles of the carbon cycle, which of the following is one explanation for why deforestation impacts global warming?
A. Through photosynthesis, land plants remove carbon dioxide from the atmosphere, thus large-scale removal of trees from the environment increases the greenhouse effect.
The removal of forests decreases the amount of carbon dioxide released during cell respiration by these plants, thus reducing the greenhouse effect.
Slash-and-burn practices commonly used in deforestation decrease the amount of carbon dioxide released into the atmosphere.
Trees are a fossil fuel like natural gas and coal, thus burning trees decreases the amount of greenhouse gases released into the
atmosphere.
Removal of trees exposes large areas of land to sunlight, which results in an overall increase in Earth's surface temperature.
What changes can humans make that can reduce their impact on the amount of carbon dioxide in the atmosphere? Select the TWO answers that are correct.
A. Limit the use of gasoline for transportation by using more fuel-efficient vehicles, carpools, and public
transportation.
A. Conserve electricity and rely more on power sources with less carbon impact, such as solar and wind energy.
Switch from electricity generated by dams that capture the energy of water as it flows downhill to energy provided by petroleum.
Consume only ethically sourced, organic produce, avoiding pesticides and genetically modified organisms.
Increase the use of natural resources such as coal and timber for industry and economic development.
