Removing Sidebar from Organic Response Thems

I would like to remove the right sidebar in my Organic Response Theme. The website is https://www.trailsofmichigan.com. I am not a programmer but can understand if someone can direct me. The code is below:

<div class="sidebar">

	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('sidebar-right') ) : ?>

		<div class="widget">
			<h4 class="title"><?php _e("Widget Area", 'organicthemes'); ?></h4>
			<p><?php _e("This section is widgetized. To add widgets here, go to the", 'organicthemes'); ?> <a href="<?php echo admin_url(); ?>widgets.php"><?php _e("Widgets", 'organicthemes'); ?></a> <?php _e("panel in your WordPress admin, and add the widgets you would like to the", 'organicthemes'); ?> <strong><?php _e("Sidebar", 'organicthemes'); ?></strong>.</p>
			<p><small><?php _e("*This message will be overwritten after widgets have been added", 'organicthemes'); ?></small></p>
		</div>

	<?php endif; ?>

</div>
