Which table best shows the impacts resulting from human activity? impact of human activities human activity impact use of manure and other organic fertilizers reduction in population of birds use of pesticides in farms increase in bird population in nearby wetlands impact of human activities human activity impact use of manure and other organic fertilizers reduction in animal population use of pesticides in farms increase in population of native insects and bugs impact of human activities human activity impact use of plastic decrease in marine animal population removal of beach grass increase in pollution of ocean impact of human activities human activity impact use of plastic increase in fish population removal of beach grass decrease in sand erosion

Table 3

Explanation:

Plastic pollution has become the biggest threat to marine life. Thousands of seabirds, turtles, fishes and other marine animals are killed each year after ingesting plastic litter. Sometimes, these animals get entangled in the plastic litter and never get out of it until they die.  

Beach grasses have also been lost as a result of human activities. They provide food and shelter to many coastline species and also stop the garbage and other debris from entering into the water.

So, use of plastic and removal of beach grasses are increasing ocean population.

Option- Table 3

Impact of Human Activities

Human Activity                       Impact

Use of plastic                               Decrease in marine animal population

Removal of beach grass       Increase in pollution of ocean

Explanation:

Dumping of huge amount of plastic in the seas and oceans has caused devastating effect on the aquatic species. It has not only deteriorated the quality of water habitat but also a lot of suspended plastic is ingested by these species which becomes detrimental to them.

The beach grasses which helps in controlling the erosion of soil also helps in reducing the runoff of pollutants . Removal of beach grass allow the pollutants to flow into the ocean bodies and cause harm to marine life.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
