Only twelve years later in 2011, the world hit a record of seven billion people. That’s roughly 150 babies born per minute worldwide-that makes the average birth rate 1.13% for 2015-2016. The human population is quickly climbing to a total of eight billion.

Humans have had the greatest impact on the planet because there are so many people that are alive in the world. For decades, humans have taken over and changed the planet in various ways. Events such as the agriculture, scientific, industrial revolutions have impacted the planet significantly. Those events help not only the population grow but also start mass deforestation, pollution and global warming. In 1999, when the population hit 6 billion it was clear that scientists found that our population was causing climate changes from CO2 emissions. The temperature of the Earth’s atmosphere is increasing. Later on the emission of greenhouse-gas became known as global warming. The planet also faces other problems, like where were all of the people going to live, grow food and make supplies, this factor led to deforestation. Pollution from agriculture, industries and every day activities destroy the …show more content…

The harmful toxins that are inhaled by animals very slowly killing them or the in the form of rainfall the toxins land on vegetation. The animals then eat the chemicals on the vegetation, once inside of the body the toxins can kill the animal. Water pollutants come from factories, oil spills and other factors; release deadly chemicals and garbage into streams, ponds and oceans. In 2010, the Gulf of Mexico’s ecosystem was suddenly in danger because of a massive oil spill from one of BP’s oil rigs. The Smithsonian Institution wrote that “an estimated 3.19 million barrels of oil” leaked into the Gulf. Millions of birds, fish and other sea creatures trapped in the toxic oil, died before help reached them from wildlife
