Once had the highest deforestation rate in the world and in 2005 still had the largest area of forest removed annually.[1] Since 1970, over 700,000 square kilometers (270,000 sq mi) of the Amazon rainforest have been destroyed. In 2012, the Amazon was approximately 5.4 million square kilometres, which is only 87% of the Amazon's original state.[2]
Rainforests have decreased in size primarily due to deforestation. Despite reductions in the deforestation rate over the last ten years, the Amazon rainforest will be reduced by 40% by 2030 at the current rate.[3] Between May 2000 and August 2006, Brazil lost nearly 150,000 km2 of forest, an area larger than Greece. According to the Living Planet Report 2010, deforestation continues at an alarming rate. But at the CBD 9th Conference, 67 ministers signed up to help achieve zero net deforestation by 2020.
Answer:
Technological developments
Answer:
D. Pond becoming more acidic to the pollution.
Explanation:
- As the universe consists of two types of loops the positive and the negative feedback loop they are thus called the reinforcing and balancing types of loops in the ecological systems. Aggravates the system
- The positive loop or the feedback may be that the pond reaction to the chemicals thus becoming more of acidic as a result of pollution
- For example, the polar ice caps form a positive loop by the increase in greenhouse gases the melt is induced due to the spread effects and that is a universal phenomenon.
- In order to balance or bring a balance, the pond must become neutral or basic.
