  1. I'm sorry I meant sound waves not radio waves, it was a bad translation
  2. bycatch in one of the reasons the population of dolphins is shrinking, but is was wondering if it could be possible to create a device that emits radio waves of a dolphins warning for a dangerous animal. and then place this device on fishing boats (e.g. tuna fishing boats) so that other dolphins in the area will go away with the result that there will be less bycatch of dolphins and this is better for the dolphin polpulation. of course bycatch consist not only of dolphins. longline fishing is also a big problem for sea turtles, sea birds (some endangered) and sharkes. but to that there are already some solutions. you have the turtle excluder device (TED) that helps turtles in bycatch to excape from the nets. is would be the best if TEDs would be obligated to every fishing boat. It should also be a rule not to fish with a lot of boats (more than the population of live can handle) on one pecific place so that the marine live in that place isn't completely destroyed. i also want to say that there is a search engine that donated 80% of its income to a tree planting program in Brazil. i know this has nothing to do with bycatch but if you search with this browser you can help the Earth.
  3. thanks for your answer and for the interresting websites. but what is your thought on an algae that takes in plastic, processes it and than stores the energy in it cells. do you think that kind of algae can be created by genetically modifying algae.
  4. The earth is heavily polluted , no question about that. So we have to find a solution. Maybe clouds could be a solution , because in clouds there lives a lot of bacteria and algae and if we could stimulate the growth of algae in clouds , more CO2 would be processed by the algae into O2. Another solution could be a ‘homemade’ cloud consisting of a plate on which algae can grow attached to drones or a hot air balloon that can bring the plate to a certain altitude. The algae would survive because it gets H2O from passing by clouds and it would take the CO2 from the polluted air and trasnfer it into O2. Also another solutions could be a genetically modified algae that uses plastic as a nutrient and converts plastic or CO2 in a less harmful or easier collectable substance.
