Health scare over backyard fracking in CanadaFracking is huge in the Canadian province of Alberta, with tens of thousands of fracking sites, earning companies billions of dollars and securing energy needs. But people living close to fracking sites are concerned about the impact of toxic chemicals used in the process. An increasing number of residents in Alberta suffer from health problems and many go to court.Improving European aid efficiencyEurope is the biggest spender on development aid worldwide, with budgets of more than 53 billion Euros annually.
