Sustainability means developing practices which protect the environment while also providing for human needs. Which of the following changes would be most helpful in achieving sustainable agriculture? A)Clearing land for agriculture by cutting down trees instead of burning them B)Rotating crops to replenish the soil with nutrients C)Tilling the ground to remove weeds and create uniform crops D)Growing crops that produce only renewable resources

Answers

The correct answer is (D)Growing crops that produce only renewable resources

The by products of the crops such as corn stovers is used to produce energy without harming the soil quality or increasing the rate of soil erosion. The crops like sunflower, canola can produce bio-oil and bio-fuel which is a renewable fuel. This type of plants should be grown so that renewable resources can be produced. This means that this practice is sustainable as it is protecting the environment and also providing resources for human needs.

Clearing land is not a sustainable practice in any form, so not A. Crop rotation is important for maintaining soil fertility, but is not necessarily sustainable. It's definitely not C. It is likely D because using only renewable resources is top notch sustainability.

Why are some of carl linnaeus's classifications of organisms incorrect

Answers

Some of Carl Linnaeus' classifications of organisms were incorrect because he classified them based off of appearances and actions instead of actual relationships. For instance, bats were classified as birds because they flew, and whales were classified as fish because they had fins and swam underwater.The mere fact that some of his classifications were off, however, does not reduce the marked effect that it had on the advancement of scientific thought in the present world.
