I need some extra line-spacing in my document, but somebody suggested me not to change it globally. In his opinion it generates some extra unwanted space before figures and equations which looks bad. I want a simple environment by which I can set some value of baseline-stretch and renew it at the end of the environment. This is my sample code -

```
\documentclass{article}
\usepackage{environ}
\usepackage{lipsum}
\NewEnviron{height}{
\renewcommand{\baselinestretch}{1}
\BODY
\renewcommand{\baselinestretch}{2}
}
\renewcommand{\baselinestretch}{2}

\begin{document}
\lipsum[1-1][1-5]

\begin{height}
\lipsum[1-1][1-5]
\end{height}

\renewcommand{\baselinestretch}{1}
\lipsum[1-1][1-5]
\end{document}
```

It seems that `renewcommand` does not renew the base-line locally. I want an environment where the baseline values will be reset to the default. How to achieve it?
