Streams face many problems. Chemicals like pesticides, herbicides, and oil can wash into the stream during storms. Dirt and debris from construction sites and bare ground cause problems too. But there is a solution. A riparian buffer zone, or an area of trees and shrubs along a waterway, can dramatically improve water quality.

You should include at least one sentence that describes how you came to that conclusion.

a vegetated buffer-strip near the water body that sheds the water and protect it from the impact of agricultural land use.

Explanation:

The intensive agricultural practices of our time continuously lead to unsustainable loss of soil, which end up in our drainage ditches together with nutrients and chemical run-off that gets our water bodies polluted. The use of riparian (stream-bank) buffer has proved to be one of the effective management techniques that can help mitigate the issue.

The techniques involves the use of a vegetated buffer-strip near the water body that sheds the water and protect it from the impact of agricultural land use. With this, a cleaner and healthier water in streams can be found.  

Explanation:

"Examples, facts, quotations and statistics are the kind of evidence a writer should use in order to support a claim or counterclaim.

A claim is the main argument of an essay. It is probably the single most important part of an academic paper.

A counterclaim is the argument (or one of the arguments) opposing the thesis statement stated in an essay.

A counterclaim and rebuttal paragraph is intended to respond to the reader's potential arguments before they are finished reading. It also shows that you have considered both sides of the debate, which strengthens your position."
