Answer:
This study is an example of a blocked design experiment.
Explanation:
Directly, we can say that a blocked design experiment is an experiment that has the object of study divided into blocks that are repeated throughout the experimental unit. In the experiment presented in the question above, we can recognize these blocks when the researcher decided to divide the coastline into 30-meter plots, installing some with breakwaters and others without. Each plot, in this case, is a block.
This type of experiment requires that all blocks are the same and be subjected to the same factors. This allows the researcher to have control of the entire experiment and obtain homogeneous results in each block. In the experiment shown above, we can see that this control has been impaired, since the coastlines to the east and west of the lake receive very different wave patterns due to the wind. This will prevent the blocks from having homogeneous results, since the action of the breakwaters will be affected differently in each block.

The deforestation is global problem and everyone losses from it, with the coasts outweighing the benefits, but there are alternatives to reverse the process.
Explanation:
The deforestation has become one of the biggest problems in the world. The destruction of the forests brings in lot of benefits, but they are short lasting, while the costs of it are terrible and long lasting. From the deforestation, both the humans and every other organism losses, and the damage done is often fatal.
The benefits consist in more agricultural land, extraction of minerals, using the wood as a resource etc, but all those things very quickly disappear and what is left behind is unusable and destroyed area. With other words, the environmental quality is significantly lowering. This can be reversed with planting trees on the place of every tree that is cut down. Also, the new trees can be fruit trees, so apart from sustaining the environment, enormous amounts of organic food for both the humans and the animals.
Areas in the world that experience dramatic losses of their forests are:
- Amazon basin
- Southeast Asia
- Congo basin
