Environmental protection and food safety were highlighted among issues concerning people's livelihood in Premier Wen Jiabao's Government Work Report delivered to the National People's Congress on Tuesday.

With dense smog and haze covering more than 10 provinces five times in January, and half of the country's groundwater polluted as revealed by media reports in February, environmental issues have triggered continued anxiety.

Wen addressed the issue in his suggestions to the country's new leaders.
