Answer:
b. wind waves, seiches, tsunami, tides.
Explanation:
The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave. Usually, the bigger the wave, the greater the wavelength.
wind waves: small waves caused by the wind. These waves tend to be small and with a short wavelength.
seiches: are usually waves on a lake or other closed water bassin. They can be pretty high from a human perspective, so they are definitely bigger than wind waves.
tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.
tides: yes, a tide can be considered as a huge wave... that's running throughout the planet. We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.

Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.
