Human impacts on the Amazon rainforest have no been very good. Humans over the centuries have been using the rainforests for their source of wood, timber and fibres for things like furniture and building products over the years. Bulldozers and other big machines are used to mow down the rainforest to collect these valuable materials. This means that we are taking away the lives, and homes of the plants and animals in the rainforests. This process is called deforestation. Deforestation has destroyed approximately 20% of the Amazon rainforest alone in the past 40 years. Rainforests once covered over 14% of the world's surface area, and now they only cover 6%. Experts say that if we keep up at this rate, that there will be no more rainforests in 40 years. This means there will be many species that will go instinct because there homes will have been destroyed. Some of the land that has been destroyed by humans is being used for grasslands to raise cattle. Another big issue with our eco-footprint is that we are wrecking the ozone. We are ruining the ozone by putting way too much pollution into it by using cars and pulp mills. There are many organizations that are trying to reduce the amount of damage we've done to the earth and trying to save the rainforests and the organisms living in it. More of us need to take part in these organizations by recycling and reducing the amount of pollution that's being put in the atmosphere. Learn more by visiting http://www.savetherainforest.org/.
