Read the argument given below and then answer the questions which follow the argument.

Unfortunately, despite the effort put into conservation by organizations and activists, their work can easily be undermined by those who have other interests. This occurs, for example, from habitat destruction, illegal poaching, to influencing or manipulating laws designed to protect species. The current form of globalization has been criticized for ignoring sustainable development and environmental concerns. For many years, critics, NGOs, activists and affected peoples have been accusing large corporations for being major sources of environmental problems. Consequently, helping species and ecosystems to survive becomes more difficult.
