Why are rainforests being destroyed?

Why are rainforests being destroyed?
Humans are the main cause of rainforest destruction. We are cutting down rainforests for many reasons, including: In 2005 and 2010 the Amazon experienced the worst droughts ever recorded. Rivers dried up, isolating communities, and millions of acres burned. The smoke caused widespread health problems, interfered with transportation, and blocked the formation of rain clouds, while the burning contributed huge amounts of carbon dioxide to the atmosphere, worsening the effects of climate change. Meanwhile, Indonesia has experienced several severe droughts in recent decades. ** The vast majority of scientists believe that human activities are contributing to climate change. By Rhett Butler

Rain Forest In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. Biologists worry about the long-term consequences. Drought may be one. Plastic Ocean Waste Levels Going Up, Study Says Photo Some eight million metric tons of plastic waste makes its way into the world’s oceans each year, and the amount of the debris is likely to increase greatly over the next decade unless nations take strong measures to dispose of their trash responsibly, new research suggests. The report, which appeared in the journal Science on Thursday, is the most ambitious effort yet to estimate how much plastic debris ends up in the sea. Jenna Jambeck, an assistant professor of environmental engineering at the University of Georgia and lead author of the study, said the amount of plastic that entered the oceans in the year measured, 2010, might be as little as 4.8 million metric tons or as much as 12.7 million. The paper’s middle figure of eight million, she said, is the equivalent of “five plastic grocery bags filled with plastic for every foot of coastline in the world” — a visualization that, she said, “sort of blew my mind.”

How Humans Affect Animals There are millions of insects, fish, amphibians, reptiles, birds and mammals, but only one kind of human. Human can do good things for animals: help save endangered species by breeding more animals and saving their environment; making sick animals healthy, and caring for animals who can no longer live in the wild. Humans can also cause harm to animals, on purpose or by accident. Habitat Destruction When humans destroy wild land to build homes, factories, shopping malls, amusement parks, garbage dumps, even to build a visitor center, store and restaurant in a park, the land is changed.

Endangered Animals List Animal endangerment is a big environmental issue, and the number of endangered animals is constantly on the rise. See the IUCN definitions of different types of animal endangerment here. Below is a list of some of the most popular endangered animals, according to the IUCN classification. Rain Forest Threats, Rain Forest Species More than half of Earth’s rain forests have already been lost forever to the insatiable human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years.

New Study Shows Plastic in Oceans Is on the Rise Scientists have come up with a new way to measure ocean trash—and the numbers are even worse than thought. In 2010, eight million tons of plastic trash ended up in the ocean from coastal countries—far more than the total that has been measured floating on the surface in the ocean's "garbage patches." That's the bad news. The even worse news is that the tonnage is on target to increase tenfold in the next decade unless the world finds a way to improve how garbage is collected and managed. The findings are part of a groundbreaking study published Thursday in Science that for the first time quantifies how much garbage flows into the world's oceans every year. Until now, most efforts to measure ocean debris have involved sample counts of plastic floating on the surface in large garbage patches in each of the world's oceans.

Rainforest Destruction What can you do to help save the rainforest? Use less paper to help save the rainforest! Paper is made from trees. If you use less paper, fewer trees will be cut down. Using less paper is easy. Use less gasoline and plastic. This Drone Startup Has An Ambitious (Crazy) Plan To Plant 1 Billion Trees A Year The world burns or cuts down about 26 billion trees a year. It replants about 15 billion. You can see the shortfall. At the moment, we're not planting trees quickly enough to combat deforestation—a problem with big implications for climate change. That's why Lauren Fletcher wants to automate the process with drone technology.

Rainforest Biomes The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group.
