Answer: c) Researchers think that stresses created by humans are the reason behind increasing numbers of elephant attacks.
Explanation:
The aforementioned article by National Geographic shows that the higher number of elephant attacks on humans are as a result of human activities that are placing stress on elephants.
Humans are increasing in population and as a result need more land for farming. This is resulting in a shrinking habitat for elephants who then encroach on human farms and are killed for it which leads to some elephants having Post Traumatic Stress Disorder and killing other humans which then continues the cycle.
Life expectancy for smokers is at least 10 years shorter than that of non-smokers. Quitting smoking before the age of 40 reduces the risk of dying from smoking-related disease by about 90%.
Answer:
Crops are now immune to many diseases and insects.
Explanation:
The constant advancement of science and technology within agriculture has been very beneficial to the better use of crops and to stimulate a better food supply, which has a beneficial impact not only on the lives of consumers, but also on the economy. One of the greatest benefits presented by this advance in science and technology is the ability to give agricultural crops resistance to pests and diseases. This is possible thanks to genetic engineering and advances in the study of agricultural entomology and microbiology, which have allowed scientists to manipulate plants to resist attack by harmful insects and microorganisms in agriculture. This resistance allows the plants to develop well and to produce products suitable for sale.
