Large nets are used to capture fish. These nets often catch unnecessary species that are not used by humans. What change could lessen the negative effect of using large nets for commercial fishing?

• exploring new and uncharted areas of the ocean where the nets can be used

• using nets in deeper regions of the oceans where different organisms live

• designing nets that release unwanted species without harming them

• decreasing the size of the nets, but using more of them
